marily for use in` association with soda fountains or other beverage dispensing devices whereby a flavoring syrup and carbonated water may be discharged simultaneously and mixed ready for use.

Another objectief the invention is to provide a mixing faucet of a design whereby in addition to dispensing syrup and carbonated water together, carbonated 'water alone may be dispensed as desired.

A still further object of the invention is to provide a mixing faucet having a novel valve construction and a novel means for.4

baffling and thoroughly. mixing togetherI the syrup and carbonated waterfpassing therethrough.

Still another object of the invention is to provide a mixing faucet of novel assembly wherein a single resilient element operates to maintain av valve actuating handle in operative position and also ope-rates to maintain the valve firmly upon its seat at all times.

Other objects andadvantages of the invention will become apparent as the description of the saine proceeds and the invention will be best understood from a consideration of the following detailed description taken in connection .'vith the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but maybe Vchanged or modified so long as such changes Serial N0. 579,315.

Referring now more particularly to the drawing wherein like numerals of reference indicate corresponding parts throughoutthe several views, the numeral 1 indicates the main body portion of the valve embodying the present invention. As shown, this body comprises a single or solidipiece of metal,

preferably of circular cross section, havingV a recess 2 formed rin one end and having this end kexteriorally reduced and provided with the screw threads 3. This reduction of the exterior diameter ofthe body forms a shoulder 4 against which abuts the largerend of the noz'zle. The other end of this nozzle is con-` stricted as indicated at 6 and within the larger end portion thereof there is formed the supporting shoulder 7 upon which is positioned the apertured conical balfle plate 8. As shown this baille plate is so arranged as to havethe concave side directed upwardly toward` the recess 2 in the adjacent end of the body 1. J

Formed through the body 1 upon the longitudinal center thereof is a valve stem bore 9 which opens through the opposite end of the body 1 as shown, which ends constitutes the top of the body. In addition to this bore 9 there are formed in the body, preferably at uiametrically opposite points, the vertical passages 10 and 11, the upper ends of which open through the top ofthe body, while the lower ends communicate with lateral passages 11 which are directed inwardly toward the center of the body and these communicate with the vertically arranged outlet passages 12 which discharge through the bottom of the body into the recessv2;

The side of the body 1 has formed therein the circular recess 13, the wall of which is screw threaded, and in the bottom of this circular recess 18 are formed the pocliets 14 eachk of which is in communication with a passage 10 through the medium of the laterally directed passages 15. The recess 13 is provided to receive one end of the tubular casing 16 through which there extends the two pipes 17 and 18 each of which has one end secured in any suitable leak-proof manner in a pocket 14. rllhese pipes 17 and 18 have the carbonated or soda water and syrup receptacles of the structure in association with which the faucet 1s used, connected therewith. Surrounding the end of the tubular easing '16 which is joined to the faucet body 1 is a shield-like body 19 which may be cast integral with the body 1 or may form a separate part thereof, as desired. This body 19 serves to space the faucet body from the structure to which the faucet is connected.

Each of the passages has screw threads thus interfering with the movement of they flow controlling screw 20.

. Disposed within the recess 2 isa valve 22 which is in the form of a cylindrical body having flat end faces.

face the stem23 which passes through the boreQ and projects a substantial distance beyond the top of the body 1 when the face of the body 22 from which it extends, vis in Vposition against the washer 241 which covers the bottom lof the recess 2. This washer 24tis Vpreferably formed of leather and has apertures 25 therein for registration with Athe outlet ends 12 of the passages 1l). rl`he top face '5 of the body 22 bears against this washer.

Thebottom face of the valve body 22 has an o enin 2G formedtlierein which opens u P g P wardly into a. relatively large chamberQ'?, the wallof which is sloping as shown. Extending longitudinally through the valve body and concentrieally disposed about the longitudinal center thereof are threer ypassages each of which is indicated'by the numeral 28,VV

thecircle u on whichrthese iassaoes are formed being of the same diameter as`r the circle upon which the, centers of the outlet passages 12fare formed so that upon turning thebo'dy 22 in the proper directiona pair of passages 28 may be brought into registration withthe passages 12 or byturning the valve in the opposite direction one only of the passages 28 may be brought into registration with one of the passaffes 12, preferably the water'delivery passage. 1

The upper end of the stem 23 is flattened f through a portionof its length as indicated top of the body 1 and there is placed about ca at 29 and isalsovscrew threaded as shown. This portion of the stein project-s beyond t ie it upon the body, the metal washer 30 against which bears the inner end ofthe valve operf ating handle vor lever 31, this end of thelever being provided with a suitable aperture to receivev the upper lend of the stein, which aperture is flattened along'V one side to engage This valve bodyy 22` `has'extending from the center of one end the fiat surface 29 thereof, Surrounding the upper endof the stem and bearing upon the inner end of the lever 31 is a coil spring 32 upon the upper end of which rests a washer 33 against which bears the under one of a pair of nuts each of which isY indicated by the numeral 34 and whielnasshown, are threaded onto the stem. By this means it will be readily seen that the handle or lever 31 is frictionally held in any position to which it is turned and also the top face of `the valve body 22 is drawn up into firm contact with the washer 24.

Covering the upper end of the body 1 is a cap 35 which is in the form of alcircular shell having the 'upper end closed, while the lower end receives a portion of the body 1 and has the edge of its wall positioned against the shoulder formedtherein. AV portion of the wall of this cap is eut away to forni the opening 37 through which the handle 31 extends. A

As will also be readily understood the side edges of this opening limit the swinging movement of the handle sol that it will be stopped in the proper position when swung in one direction to open both discharge' pasbonated water and when swung in the opposite direction to uncover a singleone of the passages 12, preferably thejwaterpassage, so as to discharge carbonated water only.V

The cap 35 is securedi-n position by one or morel screws 33 which extend downwardly through the `top thereof and enga-ge in the top of the body 1a-s illustrated in Figure 1.

In the'operation of the present faucet the body is mounted in position against the soda fountain or other structure in association with which it is used with the broad end ,of the shield 19 abutting the saine and the pipes 17 and 18 are connected with suitable syrup and carbonated water receptacles. The screws 20.111 the passages 10 are then adjusted so as topermit the desired amount of water andY syrup to flow from the Vpassages 15 andafter the other partsy are assembled in the manner shown in Figure 1 the faucet is ready for use.y

In assemblingthe faucet the valve body 22 is so positioned against the washer 2a thatV when the handle 31 extends straight forwardly from the body both of the outlet ends 12 of the passages 10 will be covered.

It will thus beV seen that when the handle 31 is swung in one direction to the limit of its movement the twol diametrically oppositelyxpositioned passages 28 of the ralvewill register vwith the passages'12 andthus permit both carbonated water and syrup to flow into ,the upperpart ofthe nozzle 5 onto the perforated baffle plate 8 from which they will then pass throughthe restricted portion 6 of the nozzle in mired condition. When the handle is swung over to the opposite side to the limit ofits movement the third aper- Y ges 12 for the drawing oil of syrupand car- Cil lture`28 will register only with the carbonated 'water ,outlet passage,vthus kpermitting the d'raW-offof carbonated- Water ,Without syrup Lmixed` therewith. p

`.lftwvilll also be readily seen from lthe fore- :going 3that the` present faucet structure is relatively simple in that only a single holdjing element maintains the Y 'movable parts thereof in operative position which element is the nut 34 on the upper end of the spring 32. 1t' Wil-l alsobe seen that this-spring 32 -lser-ves'ithe two-fold purposeV of maintaining -fthe-handle lin anyposition to which it is `inovedfand also-bydr'avving up upon the stem 23. maintains thevalve body 22 iirmly in positionegainst the Washer 2a. Thus any Wear 'of the Washer or valve body is compen- 'satedfor immediately by the spring` in 4lmain-taining the valve firmly in position.
